Question 174 Explanation:
Statement-1: TRUE: Top-down testing typically requires the tester to build method stubs.
Stub is a dummy subprogram. Stub uses the subordinate module’s interface, may do minimal data manipulation, provides verification of entry, and returns control to the module undergoing testing.
Statement-2: FALSE: Bottom up testing typically requires the tester to build test drivers.
Driver is nothing more than a “main program “ that accepts test case data, passes such data to the component(to be tested) and prints relevant results.
Driver is serve to replace modules that are subordinate to (called by) the component to be tested.
